Cervical spinal cord injury associated with ossification of the posterior longitudinal ligament

Abstract
Among 231 patients with cervical injuries treated over 12 years, 15 had cervical spinal cord injury associated with ossification of the posterior longitudinal ligament. All of them were male and most had injuries due to a relatively weak external force. Four of them underwent surgery. There was little difference in improvement of paralysis between the conservatively and the surgically treated group.
